I know how to enable operator assist in Windows 7. The issue is that when I click the initial Dial button I get a dialogue box stating modems connecting, I see the modem initialize but the connecting dialogue box never changes to the second dialogue box that tells you to manually dial your number and hit connect when you hear the carrier from the far end modem. I have tried different laptops running windows 7 and none of them work. One has a built in soft modem, one has a USB serial port connected to an external 3Com Courier modem and one has a USB modem. Everything works on Windows XP, but none of the Windows 7 machines work. I have tried this using Windows 7 Enterprise edition, and Professional edition. If I wait long enough I eventually get the 638 time out error but the modems connecting dialogue is still on the screen. If I hit the cancel button it just cancels the operation and if I dial the number and hear the far end carrier I can't get my modem to answer. I have looked at the modem log file from both a working windows XP and a Windows 7 system and they are both exactly the same up to the point of the modems connecting dialogue box, the Windows XP log shows a Dial command when I connect using the second dialogue box. Thanks in advance... Randy

Hi, I would like to verify whether you are trying to use a dial-up connection in windows 7. Have you tried to use it with another network environment to check the result. More reference: Create a dial-up or ISDN connection Regards, Vincent Wang TechNet Community Support

I need this to work with a modem on the far end. I don't have Vista or Windows 2008 to test, but I don't need to set up an ISDN connection. We use the Dial-up networking to connect to phone systems as a PPP connection and then once connected we use a proprietary software program to work on the phone switch. When we create the dialler we just use all of the default options. The dial-up connection works fine if it is a direct connect, but if I have to talk to someone to transfer me to the modem that is where the problem lies. Thanks. Randy

Hi, Here are the details of the expected behavior (as observed by XP SP3 behavior): 1. Both source and target modems are serial devices. 2. Network Connections is opened 3. Advanced menu -> Operator-Assisted Dialing is selected (enabled) 4. Dialup connection is double-clicked and dialog to connect appears 5. Dial button is clicked 6. Dialog appears: " Pick up the handset and dial (or ask the operator to dial). Press OK immediately after dialing, then replace the handset." 7. Customer picks up handset connected to line port of modem and dials live operator, operator picks up and forwards call to specified target modem 8. As soon as customer hears target modem tone he hangs up handset and clicks OK on dialog from step 8. 9. Dialog appears: "Modems connecting..." 9. Modems connect Here is the observed behavior in Win7: 1. Both source and target modems are serial devices. 2. Network Connections is opened 3. Alt key pressed which brings up menu bar. Advanced menu -> Operator-Assisted Dialing is selected (enabled) 4. Dialup connection is double-clicked and dialog to connect appears 5. Dial button is clicked 6. No dialog to pickup handset ever appears. Instead we see dialog for "Modems connecting..." 7. Modems can't actually connect because no number was ever dialed. Opportunity to dial number to live operator is not presented to user. This performance is by-design. The dialog box is not appearing because the service is running in session 0. Generally, user sessions are from session 1. Since the service is running in session 0, the dialog box wont be visible in other sessions(user sessions). This session 0 isolation was implemented right from vista.. In XP, service is running in user session and hence user is not experiencing any problems. Since this function is old and we won't fix it in Windows 7. But we could provide the workaround as below: Resolution 1. Start->Run services.msc 2. Start the Interactive Services Detection service if not already started. 3. Right-click this service and select Properties 4. Select Log On tab and enable Allow service to interact with desktop. Click OK to accept the changes. 5. Repeat step 4 for the Telephony service 6. Make the OA call: a. Click Dial on DUN dialog b. Dialog appears, select View the Message c. Session switched by system Manual Dial dialog appears d. Pick up handset and dial far-end modem, wait for far-end modem tone, click OK and hang up handset e. Click Return now system switches session back to user session. f. Modems should connect. Best Regards, Annie Gu

Thank you very much! Your instruction work and have solved my problem. Thanks again Randy

Just an update, the next time I tried to use Dialup networking, I found that the Telephony Service would not start and I kept getting a 1079 error. I managed to get it fixed by putting the logon back to This Account and using NETWORK SERVICE as the user and using my company logon password. Then I was able to start the Telephony service. After that I was still able to use the Operator Assist function, so I don't think you need to do Step 5 in your directions to use the workaround for Operator Assist, I think you just have to make sure Telephony service is running. Thanks again for the workaround.. Randy
